Influencia de tres abonos orgánicos tipo biol en la población de pulguilla en papa (Solanum tuberosum) variedad puca shungo

Abstract

The present research work entitled "Influence of three organic types of biol type in the population of pollen in potato (solanum tuberosum) variety puca shungo". It was carried out in the Experimental Teaching Farm Querochaca of the Faculty of Agricultural Sciences of the Technical University of Ambato; Located at an altitude of 2865 msnm, its coordinate is son: 01 ° 22 '02' 'South latitude and 78 ° 36'20,0 "West longitude. The experimental design was of divided plots with completely random blocks, the main plot being the bioles and subplots the doses with three replicates, where the following results were obtained: for the variable plant height 45 and 90 Days the best results were, B1D2 (sheep biol * 10% dose) and B1D3 (sheep biol * 12.5% dose) this may be due to the amount of nutrients that the biol has. In contrast, the foliar attack index variable at 45 and 90 days were: B2D2 (bovine biol * 10% dose), due to the amount of ppm of phosphorus in the biol. The best number of tubers per plant and tuber size was: B2D3 (bovine Biol * dose 12.5%), and B1D2 (Biol ovine * dose 10%), due to the characteristics of the biol. The variable weight and yield treatments that influenced were: B2D1 (Bovine Biol * dose 7.5%), it was determined that the Biol of sheep is the one of better performance possibly due to the characteristics that this Biol has.
